I guess what I'm having trouble understanding is that if the car works with the automatic VSS feeding the ECM then in turn the IAC etc and I switch transmissions and basically replace the stock buffer box with the Dakota box converting the new VSS signal to the ECM, what has changed? I'm guessing the VSS signal and pulses are relative to what gear I'm in based on revolutions and since the 700R4 isn't electric then what is the difference there also? If my only option is to have someone do it then fine but I want to at least know what needs to be done and why before I jump into it or just give up.
